5 min read

The human body is made up of approximately 60% water, highlighting its critical role in nearly every bodily function, from regulating temperature to aiding digestion. With a myriad of options available, from tap to designer bottled varieties, many wonder what is the best water to drink daily to support overall health and well-being. This guide breaks down the most common types of water to help you make an educated decision.

Quick Summary

This article explores different types of drinking water, comparing their pros and cons based on purification methods, mineral content, and cost. It weighs tap, filtered, bottled, spring, mineral, and alkaline waters to determine the best choice for everyday hydration and health needs.

Key Points

  • Filtered tap water is often the best choice: It balances cost, environmental impact, and safety by removing contaminants while retaining some minerals.

  • Bottled water is expensive and harms the environment: Most bottled water is simply purified tap water, but it carries a high price tag and contributes significantly to plastic waste.

  • Alkaline water's health benefits are unproven: Despite marketing claims, research does not support the idea that alkaline water significantly neutralizes body acid or provides substantial health advantages over regular water.

  • Distilled water is mineral-free: While it is the purest form of water, the distillation process removes all minerals, making it less suitable for long-term daily hydration.

  • Prioritize safety and consistency: The most critical factor is ensuring your water is clean and drinking enough of it consistently, regardless of the type.

Understanding the Different Types of Water

Choosing the right water can feel overwhelming, with each type touting different benefits. Understanding the source and treatment process for each is the first step in deciding what is best for you.

Tap Water

Tap water, also known as municipal water, is a common and affordable choice in many developed areas. It is regulated by agencies like the EPA in the US, which sets standards for drinking water quality. While generally safe, its quality can vary depending on location and local infrastructure. Concerns often arise regarding contaminants like chlorine, lead from aging pipes, or industrial pollutants.

Filtered Water

Filtered water is tap water that has passed through a home filtration system, which can range from a simple pitcher to a comprehensive reverse osmosis system. Filters can effectively remove contaminants like chlorine, lead, and other impurities, improving the water's taste and smell. However, some aggressive filtration methods, like reverse osmosis, can also strip away beneficial minerals. Some systems add minerals back in, offering a balanced solution.

Bottled Water

Bottled water offers convenience but is often tap water that has been purified. It is significantly more expensive and less eco-friendly due to the plastic waste generated. Concerns have also been raised about potential microplastic contamination in bottled water. While regulated by the FDA, these regulations can differ from those for municipal water.

Mineral and Spring Water

Sourced from underground aquifers or springs, mineral and spring water are often naturally rich in beneficial minerals like calcium, magnesium, and potassium. The mineral content provides electrolytes and a distinct taste. While beneficial, the mineral content can vary significantly by brand and may not be enough to meet daily nutritional needs. They are also typically more expensive than tap water.

Alkaline Water

Alkaline water has a higher pH level than regular drinking water, with proponents claiming it can neutralize acid in the body and offer other health benefits. However, the scientific evidence supporting these claims is limited and often debunked. The body’s pH is tightly regulated by the kidneys and lungs, and drinking alkaline water does not significantly alter blood pH. While generally safe, some artificial alkaline waters may lack the beneficial minerals found in naturally alkaline sources.

Distilled Water

Distilled water is created by boiling water into steam and then condensing it back into a liquid, a process that removes all minerals and contaminants. This results in very pure H2O, but it lacks the minerals that give water its taste and health benefits. Long-term consumption of distilled water is not recommended as it can pull minerals from the body and may lead to electrolyte imbalances. It is best reserved for specific applications, like use in medical equipment or irons.

Comparing Your Daily Drinking Water Options

To help you decide, here is a comparison of the different types of water based on key factors:

Feature Tap Water Filtered Tap Water Bottled Water Mineral/Spring Water Alkaline Water Distilled Water
Purity Varies by location; regulated but may contain residual contaminants. High; removes many contaminants and improves taste. High; regulated by FDA, but some concerns exist about microplastics. High; naturally filtered through earth. Can vary; naturally or artificially high pH. Highest; contains only H2O.
Mineral Content Varies by source, typically contains some minerals like fluoride. Can be low if using reverse osmosis; some systems remineralize. Varies widely by brand and source. Rich in natural minerals and electrolytes. Contains minerals that increase pH, but content varies. Zero; minerals are removed during distillation.
Cost Lowest; most economical choice. Moderate upfront cost for filter, low long-term. Highest; ongoing expense per bottle. High; ongoing expense per bottle. High; can be expensive to buy or ionize. Low cost for home distillation setup, but slow.
Environmental Impact Very low; relies on existing infrastructure. Low; reduces need for single-use plastic bottles. Very high; significant plastic waste and carbon footprint. High; relies on plastic bottles and transportation. High; same plastic waste issues as bottled water. Low; reusable equipment.

The Verdict: What's the Best Choice for You?

For the majority of people in areas with safe public water supplies, filtered tap water is arguably the best overall choice. It offers an excellent balance of purity, taste, cost, and environmental responsibility. Investing in a quality home filtration system can address any residual concerns about tap water contaminants while being far more affordable and sustainable than relying on bottled water.

However, the best option is ultimately a personal one based on your circumstances. If you live in an area with a poor municipal water supply, bottled water might be a safer, albeit temporary, solution. Those with specific health goals might explore naturally mineral-rich spring water, but a balanced diet remains the primary source for essential minerals. The key takeaway is to ensure your water is clean and safe, then choose based on your budget and preference.

Practical Tips for Optimal Hydration

  • Start with safe water: For most, this means filtered tap water. If your tap water is a concern, use a filter, boil it in emergencies, or use bottled water temporarily.
  • Drink regularly: Don't wait until you're thirsty; that's a sign you're already dehydrated. Carry a reusable water bottle throughout the day.
  • Flavor it naturally: If you find plain water bland, add slices of fruit like cucumber, lemon, or strawberries to improve the taste and encourage more drinking.
  • Monitor urine color: Pale or clear urine indicates good hydration, while dark urine suggests you need more fluids.
  • Increase intake with activity: During exercise or hot weather, your body loses more water through sweat, so increase your consumption.

Conclusion: Making the Right Hydration Choice

Choosing the best water to drink daily is a decision that balances safety, health benefits, taste, and sustainability. While the market offers a wide range of options, from purified to alkaline, filtered tap water remains a superior choice for many due to its cost-effectiveness, low environmental impact, and high quality with proper filtration. Ultimately, the most important aspect of hydration is consistency. Regardless of the type, drinking enough clean water every day is the most fundamental step toward supporting your body's overall health and vitality.
